Definitions

  • This patent relates to a pressure-activated flexible valve for use with a container for dispensing fluid material.
  • this patent relates to a pressure- activated flexible valve attachable to a printing ink cartridge that automatically opens and closes in response to pressure from the ink.
  • Modern ink cartridges for printing presses typically comprise a hollow tubular body, a moveable plunger inserted into one end, and a stationary dispensing fitment attached to the opposite end.
  • the dispensing fitment covers the dispensing end of the tubular body and also serves as a valve for opening and closing the cartridge. Ink is extruded from the cartridge when the plunger is forced toward the dispensing end either manually or, more commonly, by pneumatic pressure.
  • the valve or dispensing fitment is mounted in sealing engagement within the dispensing (top) end of the tubular body.
  • the valve serves four functions: (1) It controls the flow of ink from the cartridge when the plunger is activated. (2) It prevents the flow of ink at all other times, including during filling, transportation, storage, and installation of the cartridge on the printing press. (3) It prevents the introduction of air into the cartridge, which can cause localized ink drying at the nozzle and can effect the properties of the ink contents through oxidation or changes in viscosity. (4) It prevents the flow of ink to other areas of the dispensing fitment or printing equipment. (Ink found in these areas can dry and flake off, contaminating the ink reservoir. )
  • Ritter European Patent Document EP 1 005 999 A3 One known ink cartridge valve is that disclosed in Ritter European Patent Document EP 1 005 999 A3.
  • the Ritter valve is equipped with integrally formed elastic wall stays that serve as springs to open and close the valve in response to pressure exerted by the cartridge contents .
  • Ritter discloses a valve comprising a central body having a dome-shaped sealing portion connected to the inside of the neck of a mouthpiece by bridges, and a valve sleeve mounted over the neck.
  • the valve sleeve has an annular lip that mates with the sealing portion of the central body to close the valve.
  • the valve sleeve is equipped with the integrally formed wall stays that serve as springs. The wall stays stretch in the axial direction when the valve is subjected to internal pressure from the ink, which raises the annular lip, creating an annular opening between the sealing portion and the valve sleeve lip.
  • the Ritter valve has two moveable sealing surfaces.
  • a first sealing surface is found at the interface of the central body sealing portion and the annular sealing lip. This sealing surface controls the flow of ink out of the cartridge.
  • a second sealing surface is found at the interface of the mouthpiece neck and an annular valve sleeve wiper. This sealing surface is intended to prevent ink from leaking past the mouthpiece neck and into the area around the spring-like wall stays.
  • Yet another object of the present invention is to provide a valve that is activated by the internal pressure of the container.
  • the present invention is a pressure-activated valve for use with a container for dispensing fluid material.
  • the valve comprises an outer component and an inner component .
  • the outer component comprises a covering portion and a nozzle mounted on the covering portion.
  • the nozzle has a substantially cylindrical sidewall, a top edge, and an annular flexible portion extending radially inward from the top edge of the sidewall and terminating in a rigid annular rim.
  • the inner component comprises a sidewall and a stationary sealing portion connected to the sidewall via bridges.
  • the inner component is affixed to the inside of the nozzle sidewall and mates closely therewith.
  • the sealing portion and the rigid annular rim of the outer component cooperate to form a seal when the valve is in the closed position.
  • the sealing portion and annular rim define an annular opening through which the fluid material may flow.
  • the annular flexible portion of the outer component is configured to flex upward and outward when subjected to sufficient pressure from the container fluid material, thereby moving the rigid annular rim between a closed position to an open position.
  • the flexible portion has a substantially S-shaped cross-sectional profile.
  • the flexible portion forms part of the nozzle sidewall and works like a bellows by expanding and contracting in response to changes in the container internal pressure.
  • the container internal pressure is below a certain level (i.e. when the flexible portion is in the contracted position)
  • the rigid annular valve rim of the outer component seats against the convex sealing portion of the inner component to close the ink cartridge and prevent the flow of ink.
  • the flexible portion expands, exposing an annular opening between the valve rim and the sealing portion, which allows the flow of ink out of the cartridge.
  • both the nozzle sidewall and the annular portion extending inward from the top edge of the nozzle are flexible.
  • the nozzle sidewall and/or the annular portion flexes, exposing an annular opening between the valve rim and the sealing portion, which allows the flow of ink out of the cartridge.
  • the stationary sealing portion is attached directly to the container, and a substantially cup-shaped outer component having a flexible portion for opening and closing the valve is mounted onto the sealing portion.
  • Figure 1 is an exploded bottom perspective view of the pressure-activated flexible valve of the present invention, including a cutaway view of the outer component, shown with a plunger.
  • Figure 2 is a top exploded perspective view of the pressure-activated flexible valve and plunger of Figure 1.
  • Figure 3 is a cross-sectional view of an assembled pressure-activated flexible valve made according to the present invention, shown in the closed position.
  • Figure 4 is a cross-sectional view of the pressure- activated flexible valve of Figure 3, shown in the open position.
  • Figure 5 is a cross-sectional view of a second embodiment of the pressure-activated valve of the present invention.
  • Figure 6 is a cross-sectional view of a third embodiment of the pressure-activated valve of the present invention.
  • Figure 7 is a cross-sectional view of a fourth embodiment of the pressure-activated valve of the present invention.
  • Figure 8 is a cross-sectional view of three possible configurations of the sealing portion of the present invention.
  • the invention is a pressure-activated valve for fluid dispensing containers, such as ink cartridges for commercial printers.
  • the valve opens when acted upon by the pressurized fluid inside the container and closes when the pressure is reduced.
  • the valve has a flexible portion that acts in a spring-like fashion to open and close the valve.
  • This flexible portion may take the form of an inwardly extending ring having a wavy cross-sectional profile ( Figures 1 to 4 and 7) , a cylindrical bellows ( Figure 5) , or both ( Figure 6) . Regardless of the configuration of the flexible portion, the valve has only one sealing surface.
  • the pressure-activated valve in the attached figures is shown as it might be used with a tubular paperboard ink cartridge for dispensing printing ink, although it will be understood that the valve may be used with other types of containers, including but not limited to metal containers, squeeze tubes and bags, and with other types of fluid materials, including gases, powders, emulsions and pastes.
  • the ink cartridge is depicted with its valve or dispensing end pointing up, although the dispensing end would ordinarily point down when the cartridge is in use.
  • Figures 1-4 show a first embodiment of the pressure- activated valve in which the flexible portion takes the form of an inwardly extending ring having a wavy cross-sectional profile.
  • Figures 1 and 2 are exploded perspective views of the valve or dispensing fitment 10 and a plunger 50 which, when inserted into opposite ends of a cylindrical tube (not shown), form an ink cartridge.
  • the valve 10 has two parts: an inner (mating) component 12 and an outer component 14.
  • the outer component 14 may have an integrally formed nozzle portion 16, as shown in the figures. Alternatively, the nozzle portion 16 may be formed as a separate piece that is attached to a covering portion 18 of the outer component 14.
  • the inner mating component 12 comprises a cylindrical sidewall 20 and a preferably dome-shaped sealing portion 22 connected to the sidewall 20 by bridges 24.
  • the inner component 12 is affixed to the nozzle portion 16 of the outer component 14, for example, by means of an annular flange 26 disposed around the base of the cylindrical sidewall 20.
  • the flange 26 forms a snap fit within a channel 28 located circumferentially around the inside of the nozzle sidewall 30.
  • the bottom surface of the channel 28 is defined by detents 32 extending radially inward from the inside surface of the nozzle sidewall 30.
  • the inner component 12 may be affixed to the nozzle portion 16 of the outer component 14 by screw means, heat welding, or any other suitable means, or the inner component 12 may be an integral part of the nozzle portion 16, i.e. formed from the same piece of material. Regardless of the means by which the inner component 12 is affixed inside the nozzle 16, the inner component 12 should mate closely with the inside of the nozzle 16 to minimize wasted ink.
  • the outer diameter of the inner component sidewall 20 should be about the same as the inner diameter of the nozzle sidewall 30.
  • a sidewall 34 extends downward from the periphery of the covering portion 18.
  • the sidewall 34 fits snugly into the dispensing end of a cylindrical cartridge body (not shown in the figures) and may have a flange 36 that extends radially outward from the top of the sidewall 34 to abut the upper rim of the cartridge body when the outer component 14 is fully inserted into the body.
  • the sidewall can be extended to such a length that it serves as the cartridge body.
  • the nozzle 16 is mounted over a centrally disposed aperture in the outer component covering portion 18 and, in the preferred embodiment, comprises a sidewall 30 and an annular flexible portion 40 extending radially inward from the top edge 42 of the nozzle sidewall 30.
  • the flexible portion terminates in a rigid annular rim 44.
  • the annular rim 44 defines a centrally located opening 46. For a typical printing ink cartridge, this opening 46 is about % inches in diameter, although it can be much smaller or larger.
  • the flexible portion 40 of the nozzle 16 has a geometry and thickness that enables it to flex under pressure, from a closed position, shown in Figure 3, to an open position, shown in Figure 4.
  • the flexible portion 40 takes the shape of an inwardly extending ring having a curved or wavy cross-sectional profile, such as the S-shape shown in the Figures.
  • the flexible portion 40 comprises a convex portion 48 and a concave portion 52.
  • the convex portion 48 is shaped like the upper half of a circular toroid and the concave portion 52 is shaped like the bottom half of a circular toroid.
  • the two toroidal surfaces 48, 52 are joined at an intersection 53 and together have an approximate S-shaped cross-sectional profile.
  • the flexible portion 40 of the nozzle 16 has just been described as comprising a single convex portion and a single concave portion, it will be appreciated that other configurations would also be suitable, including configurations having multiple convex and concave portions, a convex portion only, or a concave portion only.
  • the primary requirement of the flexible portion is that it be capable of flexing between closed and open positions in response to changes in pressure exerted by the container contents and be able to maintain an adequate seal between the rim 44 and the sealing portion 22 when in the closed position.
  • the valve rim 44 seats against the sealing portion 22 to close the ink cartridge and prevent the flow of ink.
  • the sealing surface i.e., the surface where the rim 44 seats against the sealing portion 22, is shaped substantially like a truncated cone. This single sealing surface reduces the chance of leakage of material out of the container or the chance of air leaking back into the container.
  • the flexible portion 40 is pre-stressed by the sealing portion 22 when the inner component 12 is snapped into place inside the nozzle portion 16 of the outer component 14.
  • the plunger 50 is configured to mate closely with the dispensing fitment 10, thereby minimizing the amount of residual ink left in the cartridge after the plunge travels the full distance inside the container body.
  • the top surface 56 of the plunger 50 mates with the outer component covering portion 18 and the plunger central hub 58 mates with the inner component 12 and the nozzle 16.
  • the flexible portion of the valve is shaped like a cylindrical bellows, or what might be termed accordion shaped.
  • the valve or dispensing fitment 60 shown in the figure comprises an inner component 62 and an outer component 64.
